To all whom it may concern: 7

Be it known that I, ALFRED Nnwnorn, a citizen of Sweden, residing atJacksonville, in the county of Duval and State of Florida, have inventednew and useful Improvements in Attachments for Motor-Vehicles, of whichthe following is a specification.

This invention has reference to means for increasing the tractionsurface for a wheel in traveling over sand, mud, snow and soft surfaceswithout allowing the wheel to sink in such surfaces, as well as forfacilitating the extraction of wheels from rats in a road.

An object of the invention is to produce a traction surface orextricator for vehicle wheels comprising a ribbed or corrugated memberof a greater width than the wheel tire or tread surface, and which maybe easily and quickly attached to the wheel or removed therefrom asdesired.

It is a further object of the invention to produce a means forincreasing the traction surface for a wheel comprising a ribbed orcorrugated plate having means whereby the same is not only attachedaround the rim of the wheel but is supported from the hub thereof.

it is a still further object of the invention to produce a means forincreasing the tract tion surface of a wheel which may comprise astraight flexible plate designed to be readily shaped to correspond withthe contour of the tire of the wheel upon which the same is arranged,having means for retaining the same in such condition and for properlysupporting the same on the Wheel, the said device, when not in use,being applied as stated' so that one or a number thereof may be arrangedin the box below the seat of the vehicle when not required for use, ormay be otherwise stored in the vehicle and occupy but a small space.

Other objects and advantages will appear as the nature of the inventionis better understood, reference being had to the accom panving drawings,in which:

Figure 1 is a side elevation of a wheel provided with the improvement.

Fig. 2 is an edge view thereof.

Fig. 3 is a sectional view approximately I on the line 33 of Fi 1. Fig.4 is a sectioned view approximately on the line 4-4 of Fig. 1.

Fig. 5 is a sectional view approximately on the line 5-5 of Fig. 1.

Fig. 6 is a perspective view of the improvement detached from the wheel.

Fig. 7 is a sectional view showing the bolt member passing throughalining eyes in the rod and rib. I

Fig. 8 is a view of the engages with the hub.

Referring now to the drawings in detail, the numeral 1 designates anordinary vehicle wheel, the spokes 2 of which radiating in the usualmanner from the hub 3.

My improved traction surface increasing device is preferably constructedfrom a plate of flexible material, and is, as disclosed by the drawings,transverselycorrugated providing V-shaped projections and V-shapeddepressions between the said ,projections. The projections provide whatmay be termed calks, or resisting surfaces for the road bed split ringwhich over which the wheel travels.

The plate 5 is of a materially greater width than that of the treadsurface or tire of the wheel, and when in position the said treadsurface of the wheel is designed to be arranged centrally of the plate,so that the said plate projects a considerable distance beyond each sideof the wheel. The plate, at the ends thereof, and approximately at thecentral portion thereof .may be reinforced by bars 6 securedtransversely thereto, that is, upon the inner surface of the said plate.The plate, on its inner surface at its said ends and its center isprovided with spaced lugs 7 arranged in pairs, the space between thelugs being sufiicient to receive therein the tread surface or tire ofthe wheel. These lugs 7 have secured thereto flexible elementspreferably in the nature of chains 9, one of each pair of chains havingits end link provided with pivoted hooks 10 designed to engage certainof the links of the co-acting chain. The central chains are shorter thanthe end chains, and

the rods and the rin beaks 13. The links engaged by the hooks aredesigned to be received in the referred to'rounded portions 12 of thehooks proper.

As stated, the plate is constructed of resilient material so that thesame will readily lend itself to the contour of the wheel and also, whenthe same is not in use the plate may be brought to a flat condition sothat the device may be readily stored in the vehicle. Any number of theextricators or traction surface increasing members may be employed onthe wheel.

In addition to the chain connection between the extricator or tractionsurface increaser and the wheel, I have arrangcdl adjacent the endsthereof the improved pivoted rods 14 directed angularly toward eachother and having the inner ends thereof provided with eyes 15. On thehub of the wheel is a split ring clamp 16, the ends of which areprovided with eyes 17 disposed outwardly but in a line with the eyes ofthe rods. Through the alining eyes of is passed a bolt member 18, thesaid be t being engaged by a nut 19. In addition to this, I secure uponthe ring clamping member chain sections 20 and 21 respectively, one ofthe said chain sections having a hook 22, similar to the hooks 7previously described. These chain sections are designed to be arrangedaround the spokes at their connection with the hub of the wheel, and thehook is adapted to conbe readily understood.

The outside rigid supports are for the purpose of serving as auxiliaryspokes to support the surface of the plate that is disposed outward ofthe wheel ofthe vehicle, so that the weight of the load of the vehiclewill be delivered to all parts of the said plate. Also by thisarrangement the width of the plate to the outside of the wheel may bepractically unlimited.

I aving thus described the invention, what is claimed as new, is

1. A traction surface increasing means for vehicle wheels, comprising amember of greater width than the tire of a wheel designed to be arrangedon the outer surface of the tire, flexible means for securing the memberto the rim of the wheel, and rigid supporting means between said memberand the hub of the wheel.

2. A traction surface increasing means for vehicle wheels, comprising anormally fiat yieldable member of a less length than the circumferenceof a wheel and ofa width greater than that of the tire of the wheel,said member designed to be arranged on the outer surface of the tire toconform to the shape of the said tire, flexible means for securing themember to the rim of the wheel, and rigid supporting means between saidmember and the hub of the wheel.

In testimony whereof I aifix my signature.

ALFRED NEWHOPE.
